ADEN BECKETT,OF LONG ISLAND CITY, NEW' YORK.

OVEN-LOADING DEVICE.

ajpucation med spin 25, 1921; serial No. $4,131.

T 0 all whom t may concern: l

Be it known that I,v ADEN BEGKTT, a citizen of the United States, residing at Long Island City, in the county of Queens and State of New York, have invented a new and useful Oven-Loading Device, of which the following is a specification.

This invention relates to a loading device adapted for use in loading glass annealing furnaces to `insure the glassware being properly placed ywithin the furnace. t

A further obfect of the invention is to provide a rotatable rack to receive the glassware, there being provided novel means automatically operated for sweeping"v the glassware from the rack at predetermined intervals. i

A still further object of the invention is the provision of a device of this character which will receive materalfroman endless conveyor and deliver thesame to the rear of the oven.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawings Figure 1 is a vertical sectional view through the loading device and its operating mechanism, the oven in which the same is supported being shown in elevation.

Figure 2 is a plan view of the main or operating gear.

Figure 3 is a sectional view taken on line 3-3 of Figure 1; and

Figure 4 is a sectional view taken on line 4-4 of Figure l.

Referring to the drawings in detail, the reference character 5 designates the upper portion of a glass annealing furnace, the oven floor thereof being indicated by the reference character 6 and shown as supported by the brackets 7 which are secured to the inner walls' of the oven in any well known manner.

The loading device forming the subjectmatter of the present invention includes a vertical shaft 8 that extends through the hollow shaft 9, which in turn operates within the hollow shaft 10, the shafts being yshown. ias extending through a suitable "opening in the upper portion ofthe oven',:the Y lower ends thereofterminating at points directly abovethe oven floor 6, for purposes to be' hereinafter more fully described.-

Secured tothe shaft 8 and disposed adjacent tothe lowerend thereof, are-the arms 11,' which arms have connection with the circular shelf "12 vas byun'eans of the securing` bolts 13', which pass through suitable openings'inl the arms 11 and shelf l12. Theshaft 8 has its upper en'd disposed in a playneabovev *the parallel supportsr 14" that are mounted above the oven, and has connection with the relativelylarge gear wheel 15,*whicvh is pro- :vided with peripheral teeth 16 that meshrd with the teeth ofthe gear Wheel 17,` The gear wheel' 17 is mounted at the upper end of the shaft18 Aand 'carries a beveled pinion `19 atlthe lower end thereof, thebeveled pinion 19 being* in mesh the beveled pinion 20 which is keyed or 'otherwise scf cured to the horizontal power shaft 21 which in turn has connection with a suitable power device not shown.

A gear wheel 22 is keyed to thel hollow shaft 9 at a point adjacent to its upper end to impart rotary movement to the arm 23 which has connection with the lower end of the tubular shaft 9. Formed in the upper lsurface of the arm 23 is a groove 24 which has inclined walls cooperating with the inclined walls on the sliding bar 25 to guide the sliding bar 25 in its movements longitudi` nally of the arm 23. The bary 25 has a depending right angled portion 26 which has its lower entremity disposed in spaced relation with the circular shelf 12 `so that the armA may be free to move thereover.

Mounted on the supports 14 are the bracket members 27 in which are supported the shafts 28 and 29 respectively,l the shaft 29 supporting the pinion 30 which is in mesh with the pinion 31 carried at the lower end of the shaft 28` the upper end of the shaft 28 supporting the pinion 32 which is in mesh with the gear wheel 15. The pinion 30 is in mesh with the gear Wheel 22 so that rotary movement of the gear wheel 15 imparts a rotary movement to the pinion 32, which in turn transmits rotary movement to the pinion 30 through the pinion 31.

At the upper end of the hollow shaft 10 is a disk 33 which carries rollers 34 that provide bearings for the gear wheel 22 to permit the same to revolve freely, thereover, the

lower end of the hollow shaft l() providing a support for the eccentric which has a groove 36 formed in the lower surface thereof, the groove following theV contour orii the eccentric 35. Formed integral with the bar 25 is an upwardly extending shaft supporting a roller 37 which is disposed within the groove 36 so that when the arm 23 is rotated, the roller moving within thegroove 36 will cause a reciprocation of the bar 25 longitudinally of the arm 23, with the result that the right angled extremity 26 of the bar 25 is moved across the rack 12- toclear the same of ma terial positioned' thereon. y

Due to the construction and arrangement of the pinions 30, 3l and 32, it will be seen that as the pinion 32 is rotated ,in one direction, which causes the rack l2 to be moved in lone directiomthe. arm.y 23, is movedy in the opposite directionso that articles positioned on the rack l2r will be raked therefrom, at a predetermined interval, whereupon the right angled portion 26 will be moved to its normal position in a manner to avoid strikingthe remaining articles on the rack'. c

It, might be further stated'that a loading device of thischaracter may be positioned adjacent to the forward portion of an oven, and in proximity to receivematerial from an endless conveyor.

`within the groove and force material from the shelf, and means for operating the arin andy shelf in opposite directions.

2, In an oven, a loading device including .n

a rotatable shelf,` an arm carrying a reciproeating bar disposed above the shelf, a roller carried by the bar, a stationary eccentric disposed abovelthe bar and having agroove adapted toacconiinodate the roller, means for rotating thelarm to cause the bar to yreciprocate, andv means for rotating the shelf inv a direction opposite toz the direction of rotation of the arm.

f In testimony that I claim Iny own, I have hereto affixed my signature inthe presence of two witnesses.
